The human body consists of trillions of cells, including some 200 different cell types with specialized functions. Stem cells, on the other hand, do not have a specialized function and have the potential to develop into many different cell types. Under certain physiologic or experimental conditions, stem cells can be induced to become tissue or organ specific cells with special functions. How are stem cells made? Scientists primarily work with two kinds of stem cells from animals and humans: embryonic stem cells and non-embryonic "somatic" or "adult" stem cells. The Promise of Stem Cells Stem cells have the capacity to not only form different types of cells but also to keep multiplying. These characteristics make stem cells a potential renewable source of replacement cells for repairing damaged tissue and studying and treating disease and disabilities including Parkinson's disease, amyotrophic lateral sclerosis (ALS), spinal cord injuries, burns, heart disease, diabetes and arthritis. fertilized egg inner cell mass zygote undergoes division Blastocyst embryo with 200 or more cells Differentiation Embryonic stem cells can be transformed into any specialized cell type by changing the growth media or environmental conditions of the culture or by manipulating it’s genetic makeup. Implantation Once implanted in the desired organ, these cells develop into functioning cells.
